Recurrent, unilateral, isolated, idiopathic lateral rectus muscle paresis is an uncommon but well-recognized disorder in children but has not been recognized as well in other age groups. Here we are reporting a case of idiopathic, isolated, recurrent, ipsilateral sixth nerve paresis in an otherwise healthy older adult. A 46 years gentle man presented with double vision since 3 years. He had similar episodes of double vision 5 times all of which recovered completely, except the last time. On examination there was right esotropia, limitation of right abduction and a normal fundus. Diplopia and Hess charting verified partial 6th nerve paresis. The patient was investigated with a wide range of investigations to rule out tumors, demyelinating, infectious, restrictive and neuromuscular junctional causes all of which were normal. Patient underwent surgical correction of esotropia and he is asymptomatic till date and is under a close follow up.
